Specification of Letters Patent. Ptenteliune'lylSOQ.

Be it known that I, lnx A. MYSER., aciti- Zen ofthe United Sta I in the` county ofGareld andState of Colorado, have invented a new and useful Vacuuni `lilly-Trap, of which the following is a specification.

rlihe principal object of the present invention is to provide vacuum mechanism for catching iiies, and similar insects, saidmechanisin being of a character that can be placed in private dwellings `or public institutions and constituting means whereby insects can be caught in large numbers, and conveiiiently disposed of. l l y One embodiment of the invention is illustrated in the accompanying drawings,wliereiu Figure 1 is a sectional view through a portion ot' a building, c;howing the mechanism therein. Fig. 2 is a vertical sectional View on an enlarged scale through the trap Fig. 3 is an end view ofthe catching conduit. F 4 a cross sectional View through the trap. y

Similar reference numerals designate corresponding parts in all the vfigures Iof the drawings.

. in, In the embodiment illustrated, a vacuum chamber, in the form of a closed tank 5, is

employed that may be placed in any, loca-ll tion desired, where it is out offtlie vvay.` for exhausting the air Means are provided from this 4tank or chamber. In tlieppresent embodiment, this means is shown in the form? of a vacuum pump ,G having flexible connection 7 with the tank or conduit.

Oneor more traps 8 are employed, `de` pendingon 'the' character. of the sys em employed. AThus in the present embodiment, the' tank is shown in the basomelit oi a building and two of the traps are placedon the floors above'. Each trap consinsts'of an reterably a cylinder 9 of` transparent material and having an open outer casing;

end. This cylinder is tened by straps l0 to i l2 connected to the tank or chamber 5, has branches 13 connected to the casings and valves 14 are located in these branches. Heads l5 are threaded into the open ends of the casings and detachably fastened to said heads are cages 1 6. The connections between said heads and cages can be effected by any suitable means, and in the present structure, each cage is shown as detachably shown aslbein'g fasshelt ,11.- 'Alconduit tes, residing at Rifle, head.

In practice theairi's first .exhausted ,from

haemerit and for sm dences, both the trap andtank may be placed on shelves in the rooms. For the larger type of apparatus, as for instance, in hospitals, apartment houses and the like, an automatic pui'np may be employed, b'ut in any case the vacuum chamber or tank is utilized. Also the tank may be located at some central station and all the buildings in the neighborhood can be connected there- `the Iiqiparatusiis, il-

" the 'vacuunmtanl'i willbe )laced in the aller places, like resi-.

-as torinstauce aboutithe tal-iles, onthe walls ilo with bypipes andprovided with trapsV to obtain the same result-s.

From the foregoing,A it is thought that the construction, operation and many advantages of the herein described 1nvent1on will be apparent to those skilled in the art,

Without, further description, and it Will be understoodthat various changes in the size, shape, proportion andminor details of construction, may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

v.I-Iavi'ng thus fully described my invention, what I claim as new, and desire to se,- cure by Letters Patent, is 1. In mechanism for catching insects, the

combination with a vacuum chamber, of

means for exhausting'the air therefrom, an insect trap comprising an outer casing, a conduit connecting the czsing and vacuum chamber, a cage detachably mounted in the casing,` a flexible conduit comnnmicating with the interior of the cage, an insect receiving funnell carried by the free end of the flexible conduit, and means located adjacent to the funnel and movable therewith for controlling the passage of air through said funnel and flexible conduit.

2. In mechanism -for catching insects, the combination with a vacuum chamber, of means for exhausting the air therefrom, a

plurality of insect traps, each comprising an' outer casing, a conduit connected to ,".the

vacuum chamber and having branches connected to the casings, a cage detachably mounted in, each casing, a flexible conduit communicating With the interior ofeach cage and having its free end arranged to admit an insect, and' a valve located in each flexibley 40'colduit adjacent to the funnel and movable therewith for controlling the passage of the air therethrough. I

3. In mechanismy for catching insects,"v the combination withfa trap comprising a, trans` parlllltubular having an open end, (jf

alieaddetachably engaged with andclosi-ng the open end ofthe casing, a tubular cage detachably mounted 'on' the inner portion of the head Within thecasing and of less cross sectional areaand ofless length than the casmg, said cage beingllcated wholly within the casing, means for exhausting the air from the casing, a flexible conduit connected to the detachable head and communicating with the ing With said casing exteriorly of the cage, a.

valve located in the conduit, a flexible conduit communicating With the interior'ofthe cage and having an open inlet end, and a valve located at said inlet end and movable With the same.

5. In mechanism for catching insects, the combination With a vacuum chamber, of means for exhausting the air therefrom,"a stationary insect. trapv comprising an outer casing and an inner cage removably mounted in the casing, a conduit connecting ,the

vacuum chamber and the casing, said conduit communicating with said casing exte.

rierly of the cage, a flexible' conduit communicating,with the interior of the cage and having an open inletend movable to different positions with respect to the trap, and a valve located at said Ainlet end and movable therewith.

'6. In mechanism for catching insects, thecombination with a vacuum chamber, of a plurality lof' 'stationary insect traps, each comprising an outer casing and an inner cage removably mounted therein, a single conduit connecting the vacuum chamber and the various traps, said conduit having communication with the casings exteriorly of the cages, valves for separately controlling said communication, a plurality of flexible conduits leading to the interior of' the cages, and having open f'mouthed tunnels at theirlfree ends that are movable to different positions with respect to'the cages, valves located in the conduits at. said ends, and movable therewith. and means 'for exhausting the air from,

the chamber. V

liitestimmiy, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.A
